Half Life 2: Episode One vs Portal 2
Half Life 2: Episode One
Half Life 2: Episode One is the first standalone game in Valve's spin-off trilogy for its game series, Half Life. Featuring a gameplay that closely resembles Half Life 2, its namesake, this game provides loyal fans of the game a nice continuation (somewhat) in the series' storyline. Similar to Half Life 2, this game has a lot more scripted scenes as well as puzzles and strategic combat rather than simply adding in more aliens for you to fight and weapons for you to fight with.Despite its rather short game duration, Half Life 2: Episode One gives its hardcore fans something to chew on as they wait - endlessly - for a Half Life 3. And naturally, being released in 2006, the game has a more polished look. To be honest, it's a great alternative game to Half Life 2.
Portal 2
Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2.
